Philips AC4072 Air Purifier Features
Design and Looks
Impressive sharp cut edges design gives a sleek and powerful look to this air purifier. Among all other models in Philips, except for AC4372, no other model even comes close to it in the looks department. The control panel is oyster metallic while the front body is metallic white. The cavity in the unit is beautifully outlined with oyster silver color. The material of the body is the strong and durable ABS plastic. Full marks to it for the design.
CADR (Clean Air Delivery Rate) m³/h
Looks take a back-seat when your device does not properly perform the task it was bought for. An important number which you should look for most diligently when buying an air purifier is the CADR(Clean Air Delivery Rate). CADR in simple terms is a measure of the efficiency of a filter to remove a particular type of particle from surrounding air. Be it smoke,pollen or dust- a filter has separate CADR ratings for the three. Generally, only the CADR(smoke) is mentioned. The CADR ratings depend on a variety of factors ranging from fan speed, surroundings, type and size of particles, size etc.
In some Philips manuals the CADR is touted as 309. Different Philips sources quote different CADR for smoke and we have included the smaller rating of the two. It is advisable to keep the rooms closed as you do while the Air Conditioners are working, because the incoming air from outside may never give the purifier a chance to clean the room’s air completely. Different filters have different particle removing efficiency.Depending on the Airflow(speed of fan) and the CADR ratings, you can make a choice which purifier will suit your needs.
• Filters out dust /pollen: over 92% (0.3 micron)
• Removes Bacteria*: >99.9%
• Filters out Toluene: > 99.9%
Healthy Air Protect Alert and Lock
With time your air purifier would start to lose its efficiency and high performance. This is normal as the filters which work so laboriously for months have a life of them. As with any other thing filters need replacement or cleaning too. The air purifier has a mechanism wherein it alerts you in advance that the filter/s are reaching their full age and need replacement. The air purifier locks itself and stops working if you ignore its warnings. This is purposefully done to prevent excessive load on the purifier as a whole because the filters are choked to death.
Smart Night Mode
In Auto mode, the air purifier turns on or off automatically depending on the air quality. When operating in Auto mode, it automatically turns on the Night mode of operation when the light sensor senses darkness inside the room. In night mode, the lights are turned off. The air purifier operates in its quietest modes with reduced fan speed and noise levels. In case the room becomes bright again for 5 minutes or more, the air purifier resumes its normal operation again.
German Multi-Layer Filter
The Philips AC4072 air purifier comes with the proprietary VitaShield IPS technology. It removes 99.97% allergens and ultrafine particles as small as 0.02 micron (100 times smaller than the dangerous PM2.5). The Pre-filter traps the bigger particles like hair, fabric strands and house dust. The AC4072 Air purifier from Philips is a HEPA purifier with multiple layers of HEPA. The more the layers means better filtering and extended life of the filter. The HEPA filters remove ultrafine nano-sized particles like pollen, allergens, bacteria and fine dust while the activated carbon absorbs polluting gases like smoke, formaldehyde, toluene and TVOCs fumes.
The in-built particle sensor gives accurate feedback on the air quality. This feedback governs the automatic functioning of the air purifier. You can even change the sensitivity of the appliance. If you are allergic or extra sensitive to something, set the sensor sensitivity by consulting the user manual. Make sure that the air quality sensor is always clean and dry.
Just another name for the more common Turbo mode. A majority of Philips Air Purifier have this feature now. When there is a large concentration of pollutants which you want to get rid of quickly, use this mode. The fan operates at its maximum speed and helps draw in the room’s air through the filters. The five-step speed levels allow you to adjust the fan speed as suitable.
Philips AC4072 Air Purifier Comparison with other Philips models
The Philips AC4072 Air Purifier does not leave out anything except the humidifying function(Philips AC3821 has it and so does Panasonic F-VXF35A) . You must check whether the specifications mentioned in the product data sheet match your criteria. We see no good reason why you should not buy this model. If for some obvious reasons, you feel the Philips Air Purifier are costly then you can always try cheaper models from different brands. One suggestion is not to always look for cheaper alternatives as things that are cheap are not cheap for no reason. You can further Read the Reviews to make up your mind.
The most likely reason for this is that the pre-filter is dirty. You must check the pre-filter for cleanliness. Wash the pre-filter under running water and let it dry completely. Alternatively, clean it by vacuum cleaner. The other likely reason could be that the packaging material has not been completely removed from the filters.
Check if you have pressed the filter reset button. The way to do so is like this. Power ON the air purifier, press and hold the power button and simultaneously also keep the filter reset button pressed.
Yes, this is perfectly as it is intended to be. When in Sleep mode, the air purifier operates quietly and only the SLEEP light remains on. If you have set the timer, one of the HOUR lights will also be on. All lights that are on during sleep mode are dimmed to allow you undisturbed sleep.
